Reaction Steps
2-Fluoro-4-iodoaniline (5.0 g, 21 mmol) was dissolved in 20 mL dry DMF. To it were added CuCN (3.8 g, 42 mmol) and catalytic amount of CuI (200 mg). The slurry was refluxed for 1 hour. Diluted with EtOAc. Filtered through celite. Concentrated in vacuuo to yield solid 4-amino-3-fluorobenzonitrile (2.9 g, 100%). ES-MS: (M+H)+ 137.
